A 4-year-old girl presented with an eosinophilic granuloma in the cranial vault. Magnetic resonance (MR) imaging showed the mass as slightly low intensity on T1- and high intensity on T2-weighted images. The pericranial soft tissue was densely enhanced after gadolinium-diethylenetriaminepenta-acetic acid infusion. The mass was soft and successfully removed. Histological examination disclosed Langerhans' cell histiocytosis. MR imaging is useful for the diagnosis of calvarial eosinophilic granuloma with soft tissue involvement.

    • "In contrast, Takeuchi et al. reported on a case in which the surrounding dura mater is reinforced in the same manner, but reported this as dura mater invasion.[10] Regarding the enhancing effect of subcutaneous soft tissue as well, Keyaki et al. reported that this was a tumor invasion from the histopathology.[4] However, there are reports mentioning that this was a change in reactivity,[6] and a consistent consensus has not been reached.

    ABSTRACT: The problem with treatments against skull lesions of Langerhans cell histiocytosis (LCH) is that invasions often reach the bones and dura mater, making it difficult to accurately comprehend the range thereof prior to surgery. We herein report that (11)C-methionine positron emission tomography (PET) (Met-PET) carried out prior to surgery was useful in comprehending the spreading of the lesion. A 20-year-old female presented with swelling and dull pain on the left side of the head. A slightly heterogeneously reinforced tumor was observed inside the bone defect in the gadolinium-enhanced T1-wighted image upon magnetic resonance imaging (MRI) and the dura mater contacting the tumor was observed with an enhancing effect. Accumulation was poor in the center of the tumor upon Met-PET, and accumulation with a well-defined border was observed in the border thereof as well as the area adjacent to the brain. Surgical resection was performed; the pathological diagnosis was LCH. An invasion of tumor cells was observed in the dura mater with accumulation observed according to Met-PET. Moreover, the accumulation of tumor cells was observed in the area observed with accumulation inside the bone; however, the center part with poor accumulation lacked tumor cells, with fibrous tissue accounting for most parts. Met-PET was believed to be helpful in comprehending the spreading of the tumor in the surroundings of the brain surface for skull lesions.

    ABSTRACT: A 15-year-old male visited our neurological service with progressive occipitalgia. Computed tomography showed an osteolytic lesion at the occipital cranium, which grew rapidly during a month. Magnetic resonance imaging showed the lesion as low intensity on T1- and high intensity on T2-weighted images. The mass was soft and successfully removed with surrounding cranium. Histological examination revealed an eosinophilic granuloma with wide skull invasion. Immunohistochemical analysis on the specimen disclosed Ki-67 expression with labeling index of 6.2%. Relatively high proliferative activity in the present case indicates that the local replication of Langerhans' cells as well as inflammatory response contributes to the expansion of calvarial eosinophilic granuloma. This is the first report demonstrating the result of Ki-67 expression on calvarial eosinophilic granuloma.

    ABSTRACT: The radiological diagnosis of osteolytic lesions of the mandible still constitutes a challenge in some pathological conditions in which the clinical data and the case history are relatively uniform and the radiological picture is lacking in any characteristics. We reviewed the conventional radiograms of six cases of Langerhans' cell histiocytosis (LCH) of the mandible examined over the last ten years. The X-ray examinations were performed in the lateral-oblique projection to allow a view of the horizontal portion of the mandible almost completely free of overlapping images of other bone structures. We identified a series of radiological patterns for these reticulo-endotheliopathies capable of causing granuloma formed by polynuclear eosinophils, plasma cells, lymphocytes, and large mononuclear macrophages with granulopexic and phagocytic activity that proliferate in the bone tissue and can be identified as the Langerhans' cells of skin, mucosa, periodontal cavities and bone marrow. The granulomatous tissue penetrates the affected organ elements and, in its spread, it compresses, atrophies, and destroys the damaged tissue, replacing it. The alterations produced by Langerhans' cell histiocytic granuloma are most common in the skeletal system affecting, in order of frequency, the skull, the long bones of the limbs, the foot, the ribs and the spine. The oral mucosa is rarely involved. The radiological investigation of unifocal Langerhans' cell histiocytic granuloma of the mandible is essential in the study of perimandibular swelling, although diagnosis is based on biopsy alone. In addition to digital or conventional radiography, other useful examinations are bone scintigraphy, Colour Doppler US, MR and CT, which enables a correct localisation necessary for planning the biopsy and treatment.
